After seven cycles of life and death, the cold-faced God of War and his cheerful daughter-in-law went from fighting each other to being side by side. At the cost of fading memories, they saw through the conspiracy of the inner ghost and the enemy country, and understood the righteousness behind little love in the crisis of their family and country. When the God of War is willing to break the defense for her, the legitimate daughter is willing to guard the mountains and rivers for him. The cycle will eventually become a guardian, and the family and country will be reborn with love.
